Now I hope they will stop allowing characters to use scrolls of spells that are not on their spell list so every class is going to be even more unique.
Yep, I doubt it though - spamming/abuse of scrolls for non-spell casters is now pretty entrenched. I think many fights would be get significantly more challenging if they applied the correct 5E rules - that is the consequence of breaking all the existing balance in 5E with arbitrary design choices. They also won't implement something like magic item attnement for the same reason.
